  1. Non-Bison Artiodactyla Elise Barnes

  2. Artiodactyla • Even toed ungulates (hoofed animals) • Most of their weight is on two toes, may or may not have two additional toes • Includes cattle, pigs, peccary, deer, camels, etc. • Two major suborders- Suiformes and Selenodontia

  3. Suiformes • Include three living families Suidae (pigs), Hippopotamidae (hippos), and Tayassuidae (peccary) • Tayassuidae originated in N. America in the late Eocene • Common genera in N. America went extinct at the end of the Pleistocene

  4. Family Tayassuidae • Two genera found at Millennium Park- Mylohyus and Platygonus • Can distinguish the two by dental and cranial features • Platygonus is more common in late Pliocene through middle Pleistocene • Mylohyus is more common in late Pleistocene

  5. Selenodontia • Characterized by crescent shape on molars • Divided into 2 major infraorders- the Tylopoda and Ruminantia • Camels and llamas are the only living tylopod family • Ruminantia includes mouse deer, musk deer, true deer, antelope, giraffe, and cattle

  6. Family Camelidae • Camels found at Millennium- Palaeolama and Tribe Lamini • Lamines varied in size and are common from late Miocene to late Pleistocene • Palaeolama mirifica is only one in FL. It was stocky and can be distinguished by dentition. • Lamas went extinct in Florida about 11,000 yrs ago

  7. Family Cervidae • Includes deer and elk • Migrated to N. America during Pliocene and Pleistocene • Odocoileus virginianus (white-tailed deer) was found at Millennium Park

  8. Family Moschidae • Musk deer • Consisted of 5 genera in the early Miocene of North America • Found the genus Machaeromeryx at Millennium
